Abstract
The invention discloses a flexible automatic tool setting method for a numerical-control gear burnishing machine. The flexible automatic tool setting method includes that a spindle of a servo motor drives a tool to rotate at a rotational speed of 20r/min at a tool working position, the rotating tool and a fed workpiece approach to each other and overcome sliding friction force, and tooth crests of the tool slide into tooth sockets of the workpiece; the workpiece continues being fed, whether the tool is successfully meshed with the workpiece or not is determined, after the tool is successfully meshed with the workpiece, the rotational speed of the spindle of the servo motor is increased until the rotational speed of the spindle of the servo motor ranges from 50r/min to 70r/min, a cylinder performs high-pressure feeding under the control of an overflow valve, and specified clockwise and anticlockwise rotation inverted cone rolling actions are completed; tooth butting occurs between the workpiece and the tool if the tool is not successfully meshed with the workpiece, the pressure is quickly increased during tooth butting and is higher than a preset value, and a pressure sensor of the numerical-control gear burnishing machine transmits signals, so that the workpiece is withdrawn to a position separated from the fronts of the tooth crests by distances ranging from 5mm to 10mm, signals are transmitted, the workpiece is connected into a normal program, and tooth setting is carried out again. The flexible automatic tool setting method for the numerical-control gear burnishing machine has the advantages automatic control and tool setting can be implemented, the work efficiency is high, and potential safety hazards which can be caused during manual tool setting can be prevented.
Description
Technical field
The invention belongs to gear machining technology field, be specifically related to a kind of flexible automatic tool preset method of crowded teeth processing.
Background technology
Prior art, in gear, tooth cover processing technique field, process tool and workpiece tooth process is all adopted manually tooth, this traditional manually to tooth mode, pick and place part bothersome time-consuming, particularly during rolling small dimension workpiece, inloading part is extremely inconvenient, and the production preparatory period is long, and manually tooth is easily made mistakes on the one hand, hand-manipulated dangerous on the other hand, also to realizing automation, form serious restriction.
Summary of the invention
The above-mentioned technical problem existing in order to overcome prior art field, the object of the invention is to, and a kind of flexible automatic tool preset method of numerical control gear rolling machine is provided, and realizes the automation of tool setting.
The flexible automatic tool preset method of numerical control gear rolling machine provided by the invention, comprise the following steps: (1) puts into tray for work pieces workpiece, then start oil cylinder, make oil cylinder pushing slide and clamping fixture seat to the feeding of cutter operating position, thereby the tray for work pieces on drive clamping fixture seat and workpiece are to the feeding of cutter operating position, proportional servo valve is controlled speed and the displacement of feeding, and oil cylinder working-pressure is 1-2Mpa; (2) in cutter operating position, servomotor spindle band cutter is with the rotational speed of 20r/min, and the workpiece of the described feeding of the cutter of rotation and step (1) is mutually close, and both overcome force of sliding friction, and cutter tooth top slips into workpiece teeth groove; (3) workpiece continuation feeding, confirms that whether engagement is successful, after meshing successfully, improves servomotor spindle rotating speed to 50-70r/min, and overflow valve control oil cylinder is done high pressure work and entered, and completes the rotating back taper rolling of regulation; Mesh unsuccessful, workpiece and cutter generation apical tooth, during apical tooth, pressure rapidly raises and surpasses preset value, the pressure sensor of numerical control gear rolling machine sends message, makes workpiece return to the front 5-10mm of tooth top place sender, then accesses normal procedure and re-start tool setting.
The flexible automatic tool preset method of numerical control gear rolling machine provided by the invention, its beneficial effect is, speed and the displacement of the feeding of adoption rate servo valve control workpiece level, adopt overflow valve controlled pressure to change, realize and automatically controlling and tool setting, operating efficiency is high, the potential safety hazard of also having avoided artificial tool setting to exist simultaneously.
